DETAILED DESCRIPTION OF THE INVENTION

A system for remotely controlling gas appliances of the embodiment of the present invention includes a plurality of gas appliances 10, a repeater 20, a network 30, and a remote control device 40.

As shown in FIG. 1, the gas appliances in the present invention include gas water heater, gas stove, gas clothing dryer, gas fireplace, and other devices which burn gas to achieve specific functions. Typically, such gas appliance 10 has a combustor 11, a gas supply 12 and other peripheral devices. The gas supply 12 supplies the combustor 11 gas for burning. The peripheral devices here are the other elements apart from the combustor 11 and gas supply 12, in the specific gas appliance. Take the water heater for example; the peripheral devices include an igniter 13, a blower 14, and water pipe 15. Different gas appliances may have different peripheral devices. In the present invention, the gas appliance 10 further has a controller 16 and a plurality of sensors 17. The combustor 11, the gas supply 12, the peripheral devices 13, 14, 15, and the sensors 17, are all connected to the controller 16 that the controller 16 may tell the gas appliance 10 to carry out specific functions such as turning on and off the gas appliance, or changing temperature. The sensors 17 are mounted on the combustor 11, the gas supply 12, and the peripheral devices 13, 14, and 15 to detect their data when they are running, and to transmit the data to the controller 16. In the present embodiment, the gas appliance 10 further has a Zigbee transceiver 18 for communication between the gas appliance 10 and the repeater 20 via wireless transmission.

As shown in FIG. 2, the repeater 20 may be mounted indoors, which has a Zigbee transceiver 21 for communication with the Zigbee transceiver 18 of the gas appliance 10. The repeater 20 further has a processor 22, a memory 23, a port 24, a control panel 25, and a screen 26. The memory 23, the port 24, the control panel 25, and the screen 26 are all connected to the processor 22, and controlled by the processor 22. The control panel 25 may be operated by user to control the gas appliance 10 manually. The screen 26 may show the relative information about the gas appliance 10. In practice, after user operates the control panel 22, it will generate a signal to transmit to the processor 22, and then the processor 22 will transmit it to the controller 16 of the gas appliance 10 through a wireless transmission between the Zigbee transceivers 21 and 18 that, user may control the gas appliance 10 by the repeater 20, to achieve a specific function, such as turning on and off, or adjusting the flame or temperature. On the contrary, the sensors 17 will transmit signals of what they detected to the controller 16, and the controller 16 will transmit them to the repeater 20 through the same way that the screen 26 may show some information about the gas appliance 10. The port 24 may be connected to the network 30. In the present invention, the network 30 may be an internet, an intranet, a telecommunication network, or other network for long-distance communication. The remote control device 30 may be communicated with the repeater 20 through a remote control device 40.

As shown in FIG. 3, a remote control system of a preferred embodiment of the present invention includes gas appliances 10, a repeater 20, and a remote control device 40. The gas appliances 10 includes a water heater 10 a, a gas stove 10 b, a clothing dryer 10 c, and a fireplace 10 d, which are connected to a repeater 20 through a Zigbee transmission.

The remote control device 40 may be a telephone or a cell phone (we take the cell phone to be the remote control device 40 in this embodiment). The cell phone 40 communicates with the repeater 20 through a telecommunication network 30. After user dials a specific number, the cell phone 40 is connected to the repeater 20, and then user may give a command to the repeater 20 by pressing specific key(s) on the cell phone 40, or by recording a voice message. The repeater 20 will generate a control signal according to the command from the cell phone 40. The control signal includes an identification data and a command data. The identification data indicates which gas appliance should receive the command, and the command data tells the gas appliance to carry out a predetermined task. For example, when the identification data indicates that the gas stove 10 b should take the command, and the command data indicates that the gas supply 12 are to be turned on, and the igniter 13 to light a fire, such that the gas stove 10 b is turned on.

The sensors 17 detect some data regarding the gas appliance 10, such as gas flow rate, speed of the blower, temperature of the combustor, etc., and transmit these data to the repeater 20 via the Zigbee transmission. When user uses the cell phone 40 and sends a specific number to the repeater 20, it will command the repeater 20 to send the detected data to the cell phone 40. These data may be in the form of a text message or voicemail.

When the sensor 17 detects an abnormal condition, such as when the temperature is too high, a problem with gas leakage, or other situations, the processor 22 of the repeater 20 will automatically send a warning message in the form of a text message or voicemail to the cell phone 40 to notify the user.

As shown in FIG. 4, in a preferred embodiment, the network 30 is internet, and the remote control device 40 may be a desktop computer, a laptop, tablet computer, a smartphone, a PDA, or other computers that may be connected to Internet (hereunder, we take the laptop computer for example to be the remote control device 40). The repeater 20 is connected to the Internet 30 through the port 21 to connect the laptop computer 40. The laptop computer 40 and the repeater 20 are installed with specific program for communication therebetween through the Internet 30. When user executes the program and selects a command in the program, this command is then transmitted to the repeater 20 through the Internet 30, and the repeater 20 generates a control signal which includes an identification data, and a command data as described above, to appoint the specific gas appliance to carry out a specific action. For example, the identification data indicates the water heater 10 a, and the command data indicates the gas supply 12 to raise the gas flow rate that in the end, the water temperature of the water heater 10 a will be raised.

The sensors 17 of the gas appliance 10 detect some data in regards to the gas appliance 10, such as gas flow rate, speed of the blower, and temperature etc., and these data are transmitted to the repeater 20 through the Zigbee transmission. The repeater 20 will transmit the data to the laptop computer 40 through the Internet 30 that user get the real time information about the gas appliances 10 a, 10 b, 10 c, and 10 d.

When the data detected by the sensor 17 of the gas appliance is examined to be in abnormal condition, such as when the temperature is too high, or when there is a problem with gas leakage etc., the program of the laptop computer will automatically provide a warning message, either audio or with flashing light, to warn user.

The remote control system of the present invention provide user to control the gas appliances, such as gas water heater, gas stove, gas clothing dryer, and fireplace etc., without the time and distance limitation. As along as the user can connect the remote control device to a network, such as Internet, intranet, or telecommunication network etc., he/she can control the gas appliances. In addition, the system of the present invention may synchronize functions of various gas appliances in home that user may control these gas appliances by one remote control device. For example, when a user is on their way home or he/she is leaving from work, he/she can use the system of the present invention to turn on the fireplace by a cell phone or a laptop computer that, it may allow sufficient time for the fireplace to warm up the room in a house, or you are reminded that the gas stove is still turned on (or you just can't be certain) when you left home, you can use the system of the present invention to remotely control the gas stove.
